AIR AND GAS COMPRESSOR.

Specification of Letters Patent.

Patented Apr. "Z, 1914:.

Be it known that 1, MICHAEL Rinsivnn, a citizen of the United States, residing at Cincinnati, county of Hamilton, and State of Ohio, have inventedcertain new and useful Improvements in Air and Gas Com-- pressors, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to a novel construction and arrangement of valve chambers and valves, intended especially for air and gas compressors, but which may be used also in other pumps for gases or liquids.

The chief object of the invent-ion is to provide a construction, by which the large number of valves required for high speed valve area are provided for in such a manner as to produce a simple, compact'and strong compressor head with the minimum clearance spaces.

In the, accompanying drawings forming a part of this specification, there are shown for purpose of illustration, ahigh pressure gas compressor, embodying all the features of the invention in their preferred form, and a modified construction embodying the broader features of the invention, and these constructions will now be described in detail, and the features forming the invention then specifically pointed out in the claims. 7

In the drawings, Figurefl is a longitudinal central section of a double acting compressor designed especially for high pressures. Fig. 2 is a cross section on the line 2 of Fig. 1.

Referring to the drawings, A is the compressor cylinder, B the compressor piston having a piston rod 10, and C the compres-' livery chamber connecting with the delivery 13, and the outer chamber 12 is the inlet or suction chamber connecting with the suction 14, but it will be understood that these parts may be reversed, the'inner chamber 11 being used for suction with its inlet at 13 or arranged in any other suitable manner.

The valves are indicated as of a common type of automatic valves, but valves of any suitable form may be used. Each of the valves is readily accessible through openings 1, closed by caps 2 in which the screw abutments 3 for the valve casings are mounted.

It will be seen that the invention provides an arrangement. of valve chambers and valves, by which the large valve area and free flow required is secured in'a very compact construction with minimum clearance spaces, and which is excellently adapted for high pressures. lhe'conipressor dimensions both radially and longitudinally of the cylinder are as small as possible, the radial valves coming within the cylinder longitudinal dimension, and the longitudinal valves within the cylinder radial dimension, so that no increase of size for cylinder and valve chamber capacity, above that necessary for the desired capacity of the cylinder and the suction and delivery chambers, is required.

What I claim is 1. A pump cylinder-having a cylinder head formed-separately from and attached to the cylinder, said head being formed to provide suction and delivery chambers extending about the end of the cylinder and said head carrying valves arranged in annular sets, one set of valves being arranged circumferentially about theend of the cylinder and opening radially to the cylinder, and the other set being arranged at the end of and opening in line with the cylinder.

2. A pump cylinder having a cylinder head formed separately from and attached to the cylinder, said head being formed to provide an annular suction chamber and an annular delivery chamber at the end of the cylinder, one of said chambers extending circumfercntially about the end of the cylinder and having in the head an annular set of valves opening radially to the cylinder, and the other chamber arranged at the 3. A cylinder head formed separately chamber '12 in line with the cylinder having from the cylinder and having valve chamvalves opening in line with the cylinder. hers extending circumferentially of and-in In testimony whereof, I have hereunto line with the cylinder and annular sets of set my hand, in the presence of two subscrib- 5 valves, one set opening radially and the ing witnesses.
